Abstract
The utility model discloses a multi-section temperature-measuring armored thermocouple, which comprises more than two single armored thermocouples, wherein each single armored thermocouple comprises ahousing, a positive wire and a negative wire which are arranged in the housing; a thermocouple hot end is arranged at he joint between the positive wire and the negative wire which are close to the temperature-measuring position; filler is arranged in the housing; the thermocouple hot ends of the more than two single armored thermocouples are arranged in different axial positions; outer sleeves are arranged on the outer sides of the two or more single armored thermocouples; and filler is arranged in the outer sleeves as well. Through the adoption of the scheme, the single armored thermocouples are packaged in the outer sleeves according to the thermocouple hot ends arranged in the different axial positions, therefore, the temperature measurement can be performed to positions in differentlevels, and at the same time, the temperature measurement is performed to different axial positions, thereby achieving the advantages of convenient installation and use, small volume, vibration resistance and high compressive resistance.
Description
Technical field
The utility model relates to a kind of thermopair, but the armoured thermocouple of a kind of multistage thermometric of more specifically saying so belongs to the temperature instrument Instrument technology field.
Background technology
Thermopair is the temperature measuring device of making according to Seebeck effect, promptly utilizes the homogeneous conductor of two kinds of heterogeneities to form the loop, when there is the temperature difference in two ends, produces the principle of thermoelectrical potential.Because it has simple structure, the Applicable temperature scope is wide, measuring accuracy is high, easy to use, bear heat, characteristics such as the physical shock ability is strong and response speed is fast, become one of industrial the most frequently used detector unit.
Some industry is some thermometric places of chemical industry particularly, and requirement can be carried out temperature survey to the position of different levels simultaneously, promptly the temperature of different axial locations is measured.For this special situation, prior art often adopts some Zhi Danzhi armoured thermocouples, secured in parallel, the hot junction of some Zhi Danzhi armoured thermocouples are so just measured the temperature of different axial locations at different axial locations by each single armoured thermocouple.But the shortcoming of above-mentioned armoured thermocouple is: install and use inconvenience, and bulky, because the split production armoured thermocouple, thereby also there are antivibration, deficiency that compressive resistance is low.
The utility model content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind ofly can carry out temperature survey to the position of different levels simultaneously, the armoured thermocouple of the multistage thermometric of can be simultaneously the temperature of different axial locations being measured, it has easy to install, volume is little, antivibration, the advantage that compressive resistance is high.
For achieving the above object, the utility model is by the following technical solutions: a kind of armoured thermocouple of multistage thermometric, it comprises that the list more than two props up armoured thermocouple, described each single armoured thermocouple is included in housing, positive wire in housing, cathode conductor, described positive wire and cathode conductor are pyrometer fire-end near the junction of temperature measurement location, and described housing is built-in with filling material; Described list more than two props up the pyrometer fire-end of armoured thermocouple at different axial locations, and the outside that described list more than two props up armoured thermocouple also is provided with outer tube, also is equipped with filling material in the described outer tube.
Filling material in the described housing is a magnesium oxide powder, and the filling material in the described outer tube also is a magnesium oxide powder.The material of described outer tube is a stainless steel.
Adopt such scheme, the armoured thermocouple of multistage thermometric of the present utility model because the list more than two is propped up armoured thermocouple, is encapsulated in the outer tube at different axial locations by pyrometer fire-end.Like this, both can carry out temperature survey to the position of different levels simultaneously, and can measure the temperature of different axial locations simultaneously, but also have easy to installly, volume is little, antivibration, the advantage that compressive resistance is high.
Description of drawings
Fig. 1 is the structural representation of the armoured thermocouple of the utility model multistage thermometric.
Among the figure, 1-housing, 2-positive wire, 3-cathode conductor, 4-pyrometer fire-end, 5-filling material, 6-outer tube.
Embodiment
As shown in Figure 1, the armoured thermocouple of multistage thermometric of the present utility model, it comprises that the list more than two props up armoured thermocouple, and it is example that present embodiment props up armoured thermocouple with three lists, certainly can also two, four or more according to the quantity of single armoured thermocouple of actual conditions.Described each single armoured thermocouple is included in housing 1, positive wire 2 in housing 1, cathode conductor 3, described positive wire 2 and cathode conductor 3 are pyrometer fire-end 4 near the junction of temperature measurement location, described housing 1 is built-in with filling material 5, and the filling material 5 in the described housing 1 is magnesium oxide powders; Described list more than two props up the pyrometer fire-end 4 of armoured thermocouple at different axial locations, and said structure and prior art are similar.
The characteristics of the armoured thermocouple of multistage thermometric of the present utility model are: the outside of propping up armoured thermocouple at described list more than two also is provided with outer tube 6, also is equipped with filling material 5 in the described outer tube 6.Filling material 5 in the described outer tube 6 also is a magnesium oxide powder.The material of described outer tube 6 is stainless steels.
